■ Engineering data and Characteristics
Thermal Overload Relays, tripping times for selection to motors of protection degree EEx e
Relays With Standard Tripping Characteristic
When selecting a standard overload, refer to the tripping curve.
Determine the values of the starting current ratio I
which is marked on the label of the motor. The overload must trip
within the t
dition must be (20% due to tolerance) below the coordination point I

All tripping times of overload relays J7TKN-A are shorter than the
minimum values of the t
acc. to EN 50019 and therefore are suitable for all motors of protec-
tion degree EEx e. For these overload relays the selection on basis
of tripping curves is thereby not necessary.
Labels of tripping curves for each setting range, sized 148x105mm
(self-adhesive) are available on request.
Specify type and setting range.
